Overview of this book

Quantum computing is making us change the way we think about computers. Quantum bits, a.k.a. qubits, can make it possible to solve problems that would otherwise be intractable with current computing technology. Dancing with Qubits is a quantum computing textbook that starts with an overview of why quantum computing is so different from classical computing and describes several industry use cases where it can have a major impact. From there it moves on to a fuller description of classical computing and the mathematical underpinnings necessary to understand such concepts as superposition, entanglement, and interference. Next up is circuits and algorithms, both basic and more sophisticated. It then nicely moves on to provide a survey of the physics and engineering ideas behind how quantum computing hardware is built. Finally, the book looks to the future and gives you guidance on understanding how further developments will affect you. Really understanding quantum computing requires a lot of math, and this book doesn't shy away from the necessary math concepts you'll need. Each topic is introduced and explained thoroughly, in clear English with helpful examples.

12.2 Applications and strategy

What do we mean by a ‘‘quantum application’’? It’s not software where the only computer used is a quantum one. That is not possible today, nor will it be necessary or possible for many decades, or even centuries. Rather, a quantum application is a hybrid classical-quantum solution that use both kinds of hardware and software.

Industry use cases, as I touched upon briefly in chapter 1

Together with those in the other sections, these questions will help you think about use cases for quantum computing and your plan for matching them to quantum solutions:

  • Where is your classical computing taking too long?
  • Where is your classical computing too inaccurate?
  • Do you currently use HPC, High Performance Computing?
  • If so, what are the bottlenecks in your solutions?
  • Can you pinpoint areas where there is an exponential growth of necessary memory or computation time?
  • ...
